Neuropeptide Y (29-64), amide, human, is primarily used in research settings to study its role in various physiological processes. It is particularly significant in neuroscience and endocrinology research, where it helps in understanding the mechanisms of appetite regulation, energy balance, and stress responses. This peptide fragment is often utilized in experiments to explore its interactions with specific receptors in the brain, such as Y1, Y2, Y4, and Y5, which are involved in modulating feeding behavior and anxiety. Additionally, it is employed in studies investigating its potential impact on cardiovascular functions, including blood pressure regulation and vascular tone. Researchers also use it to examine its role in metabolic disorders, such as obesity and diabetes, by analyzing its effects on insulin secretion and glucose metabolism. Overall, this peptide serves as a valuable tool in advancing knowledge of neuropeptide functions and their implications in health and disease.
